Pressing the Distress button will make the Distress LED flash and will activate an intermediate acoustic signal. If the Distress button is held for at least 5 seconds the acoustic signal will stop and the Distress LED will light constantly to indicate that a Distress Alert would have been send in case Distress Test Mode had not been activated. Shortly after, the cyclic activation of the Distress Msg LED, the buzzer and the MES Fault LED will continue. The light in the Distress button can be switched off by pressing the Reset/Test button.
